Am I correct in my surmise that the tornado pictured occurred in Central Europe?
Yes, in the South-Eastern part of Hungary. And yes, such events are rather rare here: between one every few years and a couple in one year, and usually the weakest sort. In fact I think this is the very first one filmed by stormchasers (a relatively new and increasingly popular hobby here). *Lunatic*, n. One whose delusions are out of fashion.
